This book provides a historical-sociological analysis of the history of sociology in Belgium from the late-nineteenth until the early-twenty-first century. It sheds new light on the social structures that shaped and shape the orientations and work of sociologists in Belgium. The impact of three structural factors is discussed in more detail: religion, language and publication imperatives. Starting from analyses of these structural factors, this book presents a detailed analysis of the genesis and institutionalization of different sociologies in Belgium. It sheds light on the kinds of sociological knowledge that are or are not valued in Belgium. This book constitutes an important contribution to the sociological history of sociology and the development of a reflective historical sociology, and will appeal to students and scholars of social theory, as well as readers interested in the history of Contemporary Belgium.
